Environment

Enforce Server with Cloud Services enrolled and connection to Cloud Gateway is configured using Enforce to Cloud Proxy settings.

Cause

This issue can cause where an enforce server is restored using reinstallation resources to a diffrent environment where existing Enforce to Cloud proxy connection is not available.

Resolution

• The proxy server seen in the error message is restored as part of enforce reinstallation resources from previous environment which is used by enforce to communicate with Cloud Services Gateway.
• Stop Symantec Detection Server Controller Service.
• Log into to Enforce Server console and update/remove this Proxy setting from Server > Settings > General.
• Start Symantec Detection Server Controller Service.
